1.
A block is projected up an incline making an angle theta with the horizontal. It returns to
its initial position with half its initial speed. Show that the coefficient of kinetic friction is
μk = (3/5)tan(theta)
(For a 'properly formatted' version of the question, see number 3 on the attached .pdf)2.
Not entirely sure. I think it may be possible to solve this using work-energy equations or kinetics.3.
Normal Force is mgcos(theta)
How should I properly start this problem?
Thank you for your consideration.
